Herpes simplex virus type 1 virions were examined by electron cryomicroscopy, allowing the three-dimensional structure of the infectious particle to be visualized for the first time. The capsid shell is identical to that of B-capsids purified from the host cell nucleus, with the exception of the penton channel, which is closed. The double-stranded DNA genome is organized as regularly spaced (approximately 26 A) concentric layers inside the capsid. This pattern suggests a spool model for DNA packaging, similar to that for some bacteriophages. The bulk of the tegument is not icosahedrally ordered. However, a small portion appears as filamentous structures around the pentons, interacting extensively with the capsid. Their locations and interactions suggest possible roles for the tegument proteins in regulating DNA transport through the penton channel and binding to cellular transport proteins during viral infection.
